2. Connecting the GF equalizer to other audio equipment
Thanks to its balanced inputs and outputs, the GF equalizer
can be connected to any audio equipment with no problems.
Refer to the following illustrations for typical wiring examples.
Pin configurations of the inputs and outputs are specified in the
'Technical specifications' chapter.
Connecting unbalanced devices to the GF equalizer is done
easiest by using monaural phone jack instrument cables.
